• 中文摘要： Protactinium-233, separated from the irradiated thorium, was used as a tracer for the extraction study with thenoyltrifluoroacetone. From the results obtained by the variation of acidities of HCl with the constant concentration of TTA in benzene, a slope of －2 was obtained by plotting the distribution coefficients against acidities. With a definite acid concentration of HCl in the aquous solution and by the variation of TTA concentration, a slope of 4 was obtained by plotting the distribution coefficients against the concentration of β-diketone. With these results, species extracted by the following solvents into the TTA in benzene solution, the order of the extraction was found as follows:
  n-amyl alcohol>cyclohexane>chloroform>n-hexane>carbontetrachloride>benzene>nitrobenzene>hexone>cyclohexanone>n-butyl alcohol.
